    Hi Chethan,

    Have you used the GUI to confirm that you can detect objects beyond 1.1m? Either your threshold is not properly configured, or you are not executing a long range burst+listen command.

    I assume you are using the Energia GetDistance.ino example. By default, the long range measurement (preset 2) will only run when no object is detected in the short range measurement (preset 1). If an object is detected in the short range measurement, the long range measurement will be skipped. In the variables section of the GetDistance.ino sketch, you can change rule this by setting the following boolean to true:
    bool alwaysLong = false; // always run preset 2, regardless of preset 1 result (hard-coded only)
    Now, both Preset 1 and 2 will be executed sequentially.

    Be sure you are using the latest version of the Energia code (v1.0.4):
